Nebuchadnezzar: This is a regular decree, and one of the most ancient extant; and no doubt contains the exact words of Nebuchadnezzar, copied out by Daniel from the state papers of Babylon, and preserved in the original language.

I Nebuchadnezzar: After he had successfully finished his wars in Syria, Egypt, etc., and the immense improvements and buildings at Babylon, and in the enjoyment of uninterrupted peace and prosperity in his palace.

a tree: This represented his exceedingly prosperous condition, the height of his exaltation, the extent of his dominions and renown, the splendour of his kingdom, the multitude of his subjects who received protection from him, and the peace and plenty they enjoyed. Dan 4:20-26; Psa 37:35, Psa 37:36; Isa 10:33, Isa 10:34; Jer 12:2; Ezek. 31:3-18

Let his: Here a transition is made from the tree to Nebuchadnezzar, whom it represented; the tree being lost sight of, a person came in its stead. This person having lost the heart, or disposition of a man, and conceiving himself a beast, should act as such, and herd among them.

and thy dwelling: All the circumstances of Nebuchadnezzar's case, says Dr. Mead, agree so well with a hypochondriasis, that to me it appears evident the Almighty God brought this dreadful distemper upon him, and under its influence he ran wild into the fields. then fancying himself transformed into an ox, he fed on grass, after the manner of cattle; and, through neglect of himself, his hair and nails grew to an excessive length, so that the latter became thick and crooked, resembling bird's claws.

my reason: Every thing was fulfilled that was exhibited in the dream and its interpretation; and God so ordered it in his providence, that Nebuchadnezzar's counsellors and lords sought for him and gladly reinstated him in his kingdom. It is confidently believed that he was a true convert, and died in the faith of the God of Israel. Dan 4:34
